Detecting mouse clicks

[Michiel Spape]

Hi,
Three things:
- I find Task.InputMasks(1).Responses.Count more appropriate, since .InputMasks is a collection (sometimes of 1). It turns out, however, that E-Prime has no problems with that (I assume this is VB's lazy tolerance, resulting in having a hard time learning other languages).
- *It does not work*. What, E-Prime fails to show your Task slide? Or, the text is not updated? Is Task an 'unreferenced object' (called in inline)? Do you actually do something like Task.Run (otherwise I see no way of showing "Page 1 of the book"). I find calling unreferenced objects in this way not always as easy as all that, with inputmasks not responding and such. I'm sure somebody else can help better at that aspect - personally, I tend to go for referenced objects again, saving code and making the experiment more transparent. Or, finally, do you get some run-time error? 
- Why do you want to refer to "Task.InputMasks.Responses.Count" if you merely want to go to the next slide? Here's what I'd do:
1. A list with one attribute, "myPageContent", with, on level 1 "Page 1 of the book" and on level 2 "Page 2 of the book". Sequential selection, one procedure. Exit list, after 180000 (3 minutes).
In the procedure
2. A textdisplay showing the text [myPageContent]. One input object (just in the properties, no messing with inline needed), mouse, allowable {ANY}, duration 60000 (or something). 

Done, mouse click proceeds to next page, no code necessary. Obviously, you could with minimal code get it to work so that left mouseclick goes one page back and right mouseclick proceeds. 
Hope that helps,
Mich

Subject: Detecting mouse clicks

Hi,

I have a problem with a very straight-forward piece of code that I
hope you can help me with.
The task is simply to detect a mouse click (in no particular place on
the screen) in order to change the displayed text. Essentially I want
to have the subject to page through a book using the mouse for 3
minutes and then proceed to the next trial. As far as I reckon the
InLine should look something like this:

Task.Text= "Page 1 of the book"

If  Task.InputMasks.Responses.Count = 1 Then
   Task.Text= "Page 2 of the book"
End If

But it doesn't work!! I've tried add a line creating an inputmask
(Task.InputMasks.Add Mouse.CreateInputMask), but matter what I do I
cant get a response.

Does it have something to do with where I place the InLine (before
Task) and what type of object Task is (I've tried with both
TextDisplay and Slide).

I hope to hear from you.
